TRT is tricky because patients will feel an initial boost in their early treatment. They assume this feeling is their new normal, but then things level out and they go back to a more normal-ish feeling.

Severe testosterone deficiencies respond very well to treatment. Going from 55 year old to 25 year old levels isn’t as dramatic.

TRT forums are full of people with normal or low-normal who thought TRT was going to solve all of their problems and make them feel young again, only to be disappointed that they don’t really feel much of anything after a while. However, now they’re stuck on it for life because their endogenous production has dropped off.
